Question

calculate the gravitational potential energy of 50-kgs sack of rice that is 2m Above the ground using formula of Ugrav=mgh​

Answer 1

Answer:

980.0

Explanation:

Given:

m=50kg

h=2m

and we know that g=9.8ms^-2

To find:

P.E=?

Solution:

P.E=mgh

putting the values

P.E=50×2×9.8

P.E=100×9.8

P.E=980.0 J
